Patented Nov. 30, 1943 UNITED STATES VALVE FOR LIQUIDS UNDER GASPRESSURE Erik Rotheim, deceased, late of Oslo, Norway, by Erica Rotheimand Hagbarth Itotheim, heirs, Oslo, Norway; vested in the Alien PropertyCustodian Application April 15, 1941, Serial No. 388,698

, In Norway July 18, 1939 1 Claim. (Cl. 251-24) The present inventionrelates to valves for liquids which reside under gas pressure in acontainer and which are intended to be sprayed from such containers.

It is an object of the invention to provide a valve, which is verysimple in construction but which at the same time secures goodtightening properties against leakages. Valves according to theinvention are especially suitable for such liquids in which aredissolved a gas serving as expelling agent for the liquid from thecontainer.

The drawing illustrates by way of example three embodiments of the newvalve.

Figure 1 showsone embodiment, as seen from one end of the valve.

Figure 2 is a vertical section through the same, in a planeperpendicular to the plane 'of the paper in Figure 1, and

Figure 3 is a view of the springy sleeve in developed condition andshown at a smaller scale than in Figures 1 and 2.

In Figures 1 and 2 the valve body proper consists of a block I ofsuitable material, for instance of metal, provided with borings for thepassage of liquid under pressure. The inlet consists of a boring Icommunicating with another, preferably narrower, boring 3, which openson the plan top side 4 of the block. Another boring 5, similar to theboring 3, from the top side 4. communicates with the outlet Ii from thevalve, which outlet may be designed to receive a nozzle of suitableconstruction, or may if desired itself be formed as a nozzle. n thedrawing said outlet 8 is for sake ofv simplicity shown as a simpleboring. The borings I and 5 open adjacent to each v other in the topside of the block.

On the top side of the block is placed a stufi'ing disc I of suitablematerial, for instance cork. Said disc is pressed against the top side 4and thus normally closes the openings of the borings 3 and I. This iseilected by means of a springy metal sleeve 8, which is illustrated indeveloped condition in Figure 3. Said sleeve is bent or folded on itselfalong the dotted lines in Figure 3, so that the sleeve encloses theblock tightly, as indicated in Figures 1 and 2, and thus will press thedisc I tightly against the surface 4 of the block i. The body portion ofthe sleeve 0 is provided with an extension 0, which is folded as shownin Figure 2, so that said extensionwill I0 beeomeswingy.Inthesleevelthereisprovided an opening in front of the outlets of theborings 3 and 5, and in said opening is inserted a pressure button orpiston It, provided with a pin ll received in a hole in the springyextension 9.

5 Thus said extension normally is pressing the button l0 against thedisc I.

The sleeve 8 is pressed so tightly around the block I and the disc I,that the disc always tightens completely against the surface 4. If now a10 pressure is exerted against the member 9 in the direction indicatedby an arrow l2, say by means of a finger of the operator, the pressureof the button In against the disc I is obviously more or less relieved.,The liquid in the borings 2 and 3 is as previously said under pressureand such pressure is then sufllcient to raise the middle part of thedisc I a little, so that the liquid now flows out of the boring 3,passes under the raised portion of the disc I and emerges through theboring 5. When the pressure in the direction of the arrow I2 is relievedthe member 0 will again move the button III downwards and the valve isclosed.

As will be understood the boring 2 of the valve is always incommunication with a pressure container (not shown) in which is storedliquid under gas pressure. However, it is obvious that the describedvalve may be used also in the filling of such a pressure container, theboring 6 then being placed in communication with the reservoir fromwhich the filling is to take place.

. What is claimed is:

.A valve for restricting the passage of fluid under pressure, comprisinga block having fiat faces and formed with passages opening through 5 oneof said faces at adjacent points, a gasket positioned in contact withsaid one face and sealed around its edges to said one face, means forpressing said gasket against said one face to close the openings in saidpassages, said means 44) comprising a plate having a body portion infacial contact with said gasket and extending around and in facialholding contact with others of said faces, said plate being formed witha spring extension bent back over said body portion and 45' overlyingsaid gasket and openings and formed at its outer end as a handle, andmeans for transmitting pressure from said extension to said gasket.ERICA RO'IHEIM.
